"A towel is about the most massively useful thing an interstellar hitchhiker can have. You can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta…wet it for use in hand-to-hand combat…wrap it around your head to ward off noxious fumes…any man who can hitch the length and breadth of the Galaxy, rough it … win through, and still know where his towel is, is clearly a man to be reckoned with."
Douglas Adams (Author of Hitchhiker's Guide to the Galaxy) explained where the idea came from:
"I was vacationing with friends in Greece some years back. Every morning they'd have to sit around and wait for me because I couldn't find my blessed towel... I came to feel that someone really together, one who was well organised, would always know where his towel is."
